When I first saw these amorous images, I thought supermodel Stephanie Seymour had taken a young lover. But—surprise!—that is actually her 18-year-old son. How close is too close when it comes to mothers and sons?

Because this is awfully close. Especially the hand-boob action. (Benefit of doubt: Maybe it was an accident?) [Image via INF]

Here's a moment that will haunt him forever. As commenter sarasasa notes, "having a hot model mom as a teenage boy must be confusing." [Image via INF]

To his credit, there are other half-naked people present, and he's nineteen. Let us not cast judgment on the genitalia of those suffering from excess hormones. [Image via INF]

After all, every family is different. I once dated a guy whose mother would crawl in bed with him and give him back rubs. (Weirded me out.) In some families, they pee with the door open. In others, they drink freely from one another's cups. In still others, they share beds. And in still others, they hold hands... [Image via INF]

At least they look like they're having fun. I feel kind of bad intruding on their family beach play day; Stephanie's entire family, including her husband, were present, and none of them seem weirded out. (Note that he retracted his fingers in this picture.) But seriously, is this normal behavior? How close is too close between mother and son? [Image via INF, tip via james_from_cambridge]
